feat: Add inventory management feature with CRUD operations

- Implemented inventory screen to display items with details. - Added create, edit, and consume inventory screens for managing items. - Introduced consumption history screen to track item usage. - Created inventory repository and providers for API interactions. - Enhanced routing to include inventory-related paths. - Added necessary models for inventory items and consumption history. - Integrated error handling and loading states for better user experience.
